Detailed explanation-1: -At its equator, Mars has a diameter of 4, 222 miles (6, 794 km), but from pole to pole, the diameter is 4, 196 miles (6, 752 km).

Detailed explanation-2: -Mars (diameter 6790 kilometers) is only slightly more than half the size of Earth (diameter 12750 kilometers). Note the difference in color between the two planets.

Detailed explanation-3: -Earth’s circumference (the distance all the way around the equator) is 24, 901 miles (40, 075 kilometers). Its diameter (the distance from one side to the other through Earth’s center) is 7, 926 miles (about 12, 756 kilometers).

Detailed explanation-4: -Venus, the second planet away from the Sun, is Earth’s closest neighbor. It is about the same size as the Earth, a little over 12, 000 kilometers (7300 miles) in diameter.

Detailed explanation-5: -Jupiter, the largest planet in the solar system, has an equatorial radius of about 71, 000 km (more than 10 times that of the earth).
